M 2 0g of polybasic organic acid Molecular mass 600 required 100 mL of a NaOH solution for complete neutralisation Find the basicity of acid A mixture contains 1 0 mole each of NaOH Na CO and NaHCO When half of mixture is titrated with HCl it required a mole of HCI in presence of phenolphthalein In another experiment half of mixture required y mole of same HCI in presence of methyl orange Find the value of x y When Bro ion reacts with Br ion in acidic medium Br is liberated Calculate the ratio of molecular mass and equivalent mass of KBRO A volume of 12 5ml of 0 05 M SeO reacts with 28ml of 0 1M CISO which is oxidised to To what oxidation state was the selenium converted by the reaction A02558 impure sample of copper ore is dissolved and Cu is titrated with KT solution L
